Working Theory

The Magnum RemusShield Finger Sense Antitheft Immobilizer is a must-have for all boats. Our state-of-the-art Finger Touch Immobilizer prevents theft even against the most sophisticated thieves using customary computer hacking tools to overwrite stock immobilizers or unlock the alarm systems; it even prevents theft even if keys were stolen. Recently, most thieves have already had tools to fool your factory immobilizer system or bypass any alarm system. It is also very common nowadays that some thieves obtain your key by breaking in to your house or office, and they can even get clone keys made by their fellows in repair shops. RemusShield Finger Touch immobilizer is the only safe solution that will still protect your boat against all these theft scenarios.

This time-tested finger touch immobilizer has been acclaimed for over 12 years. Your Touch Control Immobilizer boasts 10-year factory warranty.

The Remusshield Finger Sense Immobilizer boasts with the service bypass keys in order to avoid revealing the location of the sensor to unauthorized persons. Each unit features Block Retardation, meaning that you are allowed to restart the engine 8 seconds after it stopped for any reason. A warning “beep” signal will sound up when the functions are changed (on / off / retarded engine-start blocking). A default 20 sec retarded engine-start blocking is preprogrammed, meaning that the engine will start with no sensor touch and stop just after 20 seconds if screws are not touched.

The Magnum RemusShield system doesn't require any extra tools, it is automatically activated once you turn off your Hirth 265HP 2.5L SS Drag EFIá Finger-sense antitheft module, and the system will never malfunction or annoy you with an unexpected engine block. The RemusShield is a Finger Sense Antitheft Immobilizer system that blocks either the cranking motor, any engine sensor, the ignition or the fuel injection system (if any), accordingly the unit will not make you enable an unauthorized person to start the engine until she or he touches either finger to the hidden screws and closes the electric circuit. After installation, all you need to start the engine is to touch two tiny hidden screws with one finger before turning on the ignition key. No one else will know where these screws are located but you. Service mode will keep you secure against undesired fraudulent people when taking your boat to a car-wash or service-shop. It’s difficult to detect by thieves, especially since they’re not expecting it. Locating the sensor may take them several hours.

functions are user friendly

This is exactly what I expected. A high quality alarm system from a high quality vendor and functions are user friendly. As I'm a total beginner I have it installed by local boat electro technician. Thanks! AAA+++

setup seemed to require special knowledge

In all honesty I'm on the edge saying I'm satisfied still I'm not, my alarm was delivered in 17 days here to Greece and setup seemed to require special knowledge from installer as opposed to the ''ease of installation'' was definitely advertized on magnum site. I live in Colorado boating in Greece at the Mediterranean Sea and recently the security has changed a lot. I went out to the islands so I could have installed this unit a month after I had needed it. Works accurately as defined but the labor install requires is not tolerable. I am nailing this immobilizer with 4 stars only.

keeps me calm that I installed this alarm

it keeps me calm that I installed this alarm system in addition to my stock immobilizer wired up to starter motor with relay and sensor are screwed under the front instrument panel in the helm I had to extedn wires but it is a neglible flaw that harness is quite short. Delivered as expected, in good condition.

I was doing some research online and came across this website seems to provide fair amount of technical information to decide buy or not to buy. I'm very impressed with my security system, install was a breeze and functions as it has to function.
